Fonts are also broken in the other direction -- they contain both Unicode
and Apple Roman mappings, but the Unicode mapping doesn't map Latin glyphs
while the Apple Roman mapping cannot cover the glyphs available in the
font. Suggestions for how to figure out the right mapping are welcome...

I suspect RH has incorporated various fixes from current XFree86 CVS which
haven't made it into Debian unstable yet. Please give current CVS a try
and see what happens there.
